Demo of some of the new features of KF-2.15 (hybrid formulas, exponential map transform, and OpenCL acceleration) and assembling zoom videos with zoomasm-1.0.
KF (Kalles Fraktaler) is fast deep zooming Free Software for escape time fractal graphics (Mandelbrot, Burning Ship, etc). Hybrid fractals combine features of multiple formulas, with a huge potential variety. The exponential map transform is optimal for rendering zoom animations (much more efficient than frames at 2x zoom levels even if the center portion is reused). OpenCL allows graphics cards to be used for calculations, which can be faster than the main processor.
zoomasm is a zoom video assembler. It takes the output of KF's exponential map zoom sequences (a series of EXR images containing raw iteration data), and reprojects them into a sequence of flat frames. It uses OpenGL shaders for customizable colouring algorithms, and has a timeline for variable speed zoom animation (key moments in the soundtrack can be synchronized to key moments in the zoom sequence).
